Since its advent in 1981, TCP has been subject to a tremendous amount of research effort
and enhancements for achieving better performance over various network environments …

A major concern in optical burst-switched (OBS) networks is contention, which occurs when
more than one bursts contend for the same data channel at the same time. Due to the …

In this paper, a novel congestion control scheme with dynamic Burst-Contention Loss
notifications in Optical Burst Switching (OBS) networks is proposed. The proposed scheme …

TCP performance over bufferless Optical Burst Switched (OBS) networks could be
significantly degraded due to the misinterpretation of network congestion status (referred to …

For optical burst-switched (OBS) networks in which TCP is implemented at a higher layer,
the loss of bursts can lead to serious degradation of TCP performance. Due to the bufferless …

Due to the bufferless nature of optical burst switched network, contentions occur even at low
traffic loads, leading to burst losses. Contention resolution schemes, such as burst …

Random contentions occur in optical burst-switched (OBS) networks because of one-way
signaling and lack of optical buffers. These contentions can occur at low loads and are not …

Study of TCP performance over OBS networks has been an important problem of research
lately and it was found that due to the congestion control mechanism of TCP and the …

In optical burst-switched (OBS) networks, the loss of burst containing a number of IP packets
occurs mostly due to contention rather than congestion so that a TO (Time Out) event will …

Due to the bufferless nature of OBS networks, random burst losses may occur, even at low
traffic loads. For optical burst-switched (OBS) networks in which TCP is implemented at a …
